How do i learn to trust women again?

Almost every woman i have ever met lied to me. I've met someone i really like, but my pavlovian conditioning won't let me trust her.
This girl is fucking perfect for me, the best I've met in fucking years. If i could trust her it would be awesome. What the fuck do i do? I know it's kinda lame posting this here, but when we aren't trolling milkribs, i see some intelligent posters and value your opinions.

If you want commitment, you need to take advantage of whatever is in society that promotes it.  Depending where you live, it could be arranged marriage, social or legal consequence to fornication and adultery or whatever.  If you just keep bouncing from chick to chick screwing, like a pinball, with no push to commitment, it's no surprise someone screws on someone else sooner or later.  Either get a formal commitment, or just enter into an agreement that you'll both be screwing around.  Maybe you could go to orgies and shit together.  But don't get sucked into the limbo of expecting commitment when you've both been bouncing from gonad to gonad and wondering if you'll stick better this time.

I don't know why you've had such bad luck with girls, it seems you just keep going for the dishonest common as muck types. You need to set your standards a bit higher, not in terms of attractiveness but in terms of girlfriendability. Make sure you spend 6 months getting to know them inside and out, then ask them to be your girlfriend. Make sure they're devoted and awesome. Don't go into these 3-6 month contracts, they suck and you'll just lose faith in females to the point where you're single for the rest of your life. So like, be a bit more open but at the same time make sure she's the one before commiting.
